The hydrochloride salt form of ulimorelin, a macrocyclic ghrelin peptidomimetic, with potential gastrointestinal (GI) prokinetic activity. Upon intravenous administration, ulimorelin binds to the ghrelin receptor in the GI tract and may stimulate GI motility. Ghrelin is a natural ligand for growth hormone secretagogue receptors and is normally localized in the proximal GI tract. The ghrelin receptor signaling pathway mediates multiple GI functions, including motility and gastric emptying. Check for active clinical trials using this agent. (NCI Thesaurus)
